Hello,
I think there are quite some potential Wine users for C7 that would like working packages that can actually run Windows programs over EPEL 64-bit only build.
Here's my Copr project for Wine 2.0 stable series that includes complete i686-only packages for x86_64 CentOS 7:
https://copr.fedorainfracloud.org/coprs/hifi/wine-backport/At this point it does *not* depend on EPEL so you can install them on a clean CentOS 7 x86_64 system.
Please do note the description for features that differ from Fedora Wine packages.
